Not the first person to lose it there, guy on here did the same thing last year. Same with every track, worst place to have an incident is on the pit straight because there is always a wall there.
Ironically if he'd not steered into the slide to correct, it probably would would've spun on the spot and not touched the grass at all. This is why I run a £2k shed as a track car, just in case. Was he insured do you know?
Remember kids, if you're going to touch the grass always do it in a straight line, never at an angle.
